To all whom it may concern:

Be it known that I, WALTHER FELD, a subject of the King of Prussia and the German Emperor, of Honningen-on-the Rhine, in the Kingdom of Prussia and German Empire, have invented new and useful to which my invention relates being of the kind in, which, as hitherto constructed, a vessel, or vessels, is, or are, employed containing, or each containing, a rotatable device comprising a number of concentric funnels, or short conical pi es, (which I will hereinafter refer to as unnels), the upper peripheries of which are superposed to one another from outside to inside, the said funnels dipping into the liquid in the vessel and extending above the said liquid, so' that, on rotating the funnels, they will, under centrifugal action, elevate the liquid and distribute it in the form of spray across the whole of the space through which the gases, or Vapors, pass. This arrangement, although very effective, has disadvantages, which it is the object of my present invention to obviate. Supposing such device to have, say, for example, nine conical funnels arranged concentrically; the inner ones of course have a much smaller diameter than the outer ones, the diameter progressively increasing from the innermost funnel to the outermost funnel, so that, in rotating, the liquid-lifting power of the outer funnels is greater than that of the inner funnels, the lifting efl'ect diminishing progressively from-the outermost funnel to the innermost funnel, and the outer funnels are more effective in spraying than the inner ones. As the depth of the layers of liquid upon the outer funnel is so considerable that the velocity of'the different layers of liquid ascending by centrifugal action is different according to the distance of the layersfrom the rota t1ng funnel itself, the layer of liquid whlch is in con tact with the funnel having, when it arrives at the upper periphery of the funnel nearly the same velocity as the funnel, wh1ch velocity is necessary to throw the hquld hor1-, zontallyacross the space. Those layers of liquid which are not'm contact with the cone itself have far less velocity than the funnel and therefore as soon as they have come to the upper periphery of the funnel, instead of being thrown out horizontally, they have a tendency to be so acted upon by gravity that the liquid is not thoroughly spread horizontally, but is thrown out in large drops, which take a course inclined downward. This disadvantage gradually diminishes from the outermost to the innermost funnels, but the inner funnels have the disadvantage that, in consequence of their diameter bein considerably smaller than the diameter'of the outer funnels, the quantity of liquid lifted and also the peripheral velocity of the upper edges of the inner funnels are considerablyless than is the case with the outer funnels, and therefore the spraying eflect'of the inner funnels is small compared with that of the outer funnels, and the spraying effect of the complete set of funnels as a whole is not the best posslble. According to. this invention, these disadvantages ar overcome so that the amount of liquid lifte and distrlbuted is, as much as possible, equally'divided so that the llquid is practically equally sprayed across the case.

I will describe my invention with refers ence to the accompanying drawing.

Figure 1 is a vertical section of a vessel in which the funnels rotate. Fig. 2 is a sectional plan of the vessel; Fig. 3 is a modification; Fig. 4 shows a vertical section of two superposed vessels with a Pelouze tar separating apparatus superposed only the lower part of this apparatus bein shown. Figs. 5, 6 and 7 show various modifications in the form of the improved funnel.

According to this invention the outermost funnel 1 is extended so that its outer periphery is nearly at the same level as, or at a higher level than, the upper periphery of the innermost funnel 2. The part of the outer funnel which extends above the waterlevel is perforated as shown at 3. This arrangement is so effective that only one .per-

forated funnel without any inner funnel may be used, or, if the efiiciency is to be increased, beyond that obtainable by one funnel, the number of the inner funnels can be considerably diminished and, in any case, the s raying effect of the arrangement 1s considerably better than hitherto, the inner funnels when used merely serving the purpose of supplying the perforated upper part of the outer funnel with liquid. I have shown four concentric funnels as being used. In the case of two, or more, concentric funnels being used, the perforated extensions of the outer funnel may be less than is suflicient to extend above the upper periphery of the inner funnel, or funnels, 2. In this case,

all, or part, of the inner funnels may be clined superposed perforated part, extending above the liquid. Figs. 5, (3 and 7 show funnels made according to these modifications, Fig. 5 showing a perforated upper part more inclined than the lower part, Fig.

6 an enlarged curved perforated upper part,

and Fig. 7 a horizontal partbetween the lower part and the enlarged upper part.

There is another disadvantage incidental to the rotating concentric funnels as hitherto used, by which the spraying efiiciency is prejudicially affected, as, by the rotation of the funnels in the liquid, the liquid is also rotated and pressed, by centrifugal action, against the walls of the vessel so that the level of the liquid in the inner part of the vessel is lowered and therefore the liquid supply to the inner funnels is insuflicient. According to my invention I overcome this disadvantage by the use of obstructers which suppress partially, or completely, the rotation of the liquid in the vessel. Such obstructersfpreferably each consist of a radial rib, or o ber of such ribs being formed on, or fixed to,

the floor of the vessel and upstandin in the liquid sufficiently to partly, or-wholI prevent rotary movement of the liquid. In Fig. 2 I'have shown eight radial ribs and in Fig. 3 four radial ribs, but any other suitable number and shape of radial ribs may be used. I have foundthat it is sutiicient if the rotation of the liquid is prevented at the lower part of the vessel by a radial rib, or radial ribs, running from the center of the vessel underneath the innermost cone radially toward the wall of the passagefor the gases, or vapors, as illustrated,-being sufficient to obviate the disadvantageous change of liquid level, as with "such rib, or ribs,'the level of the liquid in the mid-part of the vessel is nearly the same radial ribs, 4, "any suitable num-' when the device is rotating as when it is at rest, and the efficiency of the inner funnels is greatly increased. 5

There may be one vessel, or any suitable number of vessels, superposed, with spraying devices as described in each vessel, and the apparatus can be conveniently made up in sections, each carrying such an arrangement and superposed and luted together and driven by gear 5 as illustrated.

The apparatus may be used for any purposein which gases, or'vapors, are treated with liquids. If it be used for the extraction of tar from coal gas, or the like, there may be, connected with the vessel, or the top vessel of a number of superposed Vessels, an apparatus known as the Pelouze, or Pelouze-Audoine, apparatus for the removal of the last traces of tar, this apparatus being conveniently superposed, the lower part of such an apparatus being indicated at 6 in Fig. 4. I
